6 people were waiting in line for tickets. Then 2 more people got in line.
How many people are waiting in line now? 6+2=8, can use a number line!
Chapter 12: Standard Algorithm

A step-by step way to solve a problem. Can be used for many different
types of math problems. 62-27=35.

It's like counting where you keep the number in your head and add on to it.
The jump strategy involves adding or subtracting numbers by jumping over
numbers on the number line.
Standard Form
Give this one a try later!
Standard form is writing down a number between 1 and 10, then writing x10
to the power of a number.
Write 5,000 in standard form.
5 X 10 to the 3rd power= 5,000
Benchmark numbers
